Abstract (en)

[origin: WO0156798A1] An ink jet printing apparatus includes a print head having a nozzle array (N1-N320) and which scans across the print medium in a scan direction. The nozzle array includes first and second substantially columnar nozzle arrays (34, 36), each aligned with a print medium advance direction. Each substantially columnar array has an upper subarray pair including an upper left and an upper right subarray of nozzles (C84, C83; C74, C73), each including a substantially linear arrangement of n nozzles having equal nozzle-to-nozzle spacings. Each upper right subarray is offset from the corresponding upper left subarray in the scan direction by a first spacing and in the print medium advance direction by one-half of the nozzle-to-nozzle spacing. The second substantially columnar array of offset from the first substantially columnar array in the second direction by a second spacing and in the print medium advance direction by one-forth of the nozzle-to-nozzle spacing.
